HGL36100CU44X Square D PowerPact H 100A 3-Pole 600V Breaker — MicroLogic 6.2A LSIG, 100% Rated

HGL36100CU44X Square D PowerPact H 100A 3-Pole 600V Breaker — MicroLogic 6.2A LSIG, 100% Rated

Need a 100A, 3-pole PowerPact H breaker with electronic trip? The HGL36100CU44X is the one. It mounts as a unit breaker with mechanical lugs on both line and load, so it drops straight into your switchboard or panelboard, and it's rated for reverse-fed setups when you need them. The MicroLogic 6.2A trip unit gives you full LSIG — long-time, short-time, instantaneous, and ground fault — plus an ammeter right on the breaker so you can read load current without pulling a meter.

Because it's a 100%-rated breaker, you can run it at full nameplate continuously — no 80% derate to work around when you're sizing the feeder. Interrupting capacity is G-tier: 65kA at 240V, 35kA at 480V, 18kA at 600V.

Common Applications

• Feeder and branch protection in commercial and industrial panels
• Direct replacement for existing H-Frame MicroLogic breakers
• Circuits that need ground-fault protection built into the breaker
• Full continuous-load feeders where an 80% breaker won't cut it
• Motor and HACR equipment feeds

Key Features

• MicroLogic 6.2A trip: Field-adjustable LSIG protection with an on-board ammeter.

FAQ

Will this drop into my H-Frame panel? Yes — it's a unit-mount H-Frame breaker with standard line and load lugs.

Can I reverse-feed it? Yes, the HGL36100CU44X is suitable for reverse-fed applications.

Does it have ground-fault protection? Yes. The MicroLogic 6.2A is a full LSIG trip unit, so ground fault is built in.

What's the interrupting rating? 65kA at 240V, 35kA at 480V, and 18kA at 600V.

Electronic or thermal-magnetic? Electronic. The CU44X build is MicroLogic 6.2A and 100% rated, not the thermal-magnetic HGL36100.

What wire does it land? AWG 14–3/0 aluminum or copper on the standard lugs.
